Happened to me, I replaced to a new sensor. The light still came on for awhile, but later disappear for good. May be the ECU needs some times to adjust!?
My W124 260-E 1988 Mercedes' central lock control electric pump needs a check out so I would like to know what is the correct amount of vaccum (mmHg) the pump should make? and what is the correct amount of air pressure the pump should make? thanks for your help.
I checking my auto trans fluid: the fluid's color and level are okay, but usually there are always some small traces of dark metallic debris or tiny fine metallic particles on the dip stick around the top of fluid level, but the fluid itself are clean. Is this okay? normal wear or excess wear? thanks for your answers!
MY 1995 chevy lumina-sedan intermittenly shows ABS AMBER light on, after start up and first forward motion, with shorten brake cylinder motor self-test. But sometime okay! There is a port for the ABS scanner, like that of ECM, but what type of ABS scanner to use? thank you!
My GM 3.1L V6 has 4T60E auto transmission, which got about 85K miles on it. It has 1-2 band applied during overdrive range 1st gear, what does this 1-2 band do for 1st gear? Note: 3-4 gear, no band applied. Thanks!
My GM Chevy Lumina-sedan 3.1L V6 has 4T60E auto transmission with a number of its solenoids. What is the TCC PWM SOLENOID? Is it different from the shift solenoid A&B? and the transaxle converter clutch solenoid/relay? what should be their ohm resistances' values, from using digital volt. meter? Thank you for your advice!
AFTER DRIVEN HOME (15-20 MILES)FINE AND 2-HOUR BREAK, MY Lumina-sedan 3.1L V6 AUTO TRANSMISSION, 4T60-E, WOULD NOT ENGAGE/RUN IN DRIVE AND OVERDRIVE POSITIONS, BUT RUN IN REVERSE, 1&2 (FORWARD) POSITIONS! THE TRAN. FLUID HAS BEEN RECENTLY REPLACED, AT OK LEVEL, AND IN GOOD CONDITION (REDDISH COLOR). THE NEUTRAL SAFETY/START SWITCH ON TRANSMISSION BODY, HAS BEEN INTERMITTENLY MALFUNCTIONING, SO IT IS BY PASSED FOR THE ENGINE IGNITION. YOUR ADVICE WILL BE APPRECIATED1, THANKS.
Recently while idleing at stop after travelling for some distances, my 3.1L V6 Chevy engine stumbled or stalled, but did not quit or die. There was also metallic clicking noises during stalling! The engine OBD I scanner showed trouble codes 37 (TCC brake switch stuck "ON") and 82 (3X crankshaft position sensor signal error). Since the clicking noise sounded like EGR's solenoid clicking, and engine stumbled or stalled, can any of these codes cause the EGR's solinoid clicking and intermitten opened? Thanks for your advice!
My chevy 3.1L V6 95 engine recently has high-idle RPM ( about 1500), which last unusually long time, after the engine got first started in the morning after an over-night park. After that, the idling RPM seems fine. Prior to this, the first start-up idle RPM sometimes fast settled to normal RPM, but sometimes slower. The IAC valve's terminal resistances has been checked okay according to a specification. And the morning temperature has not varied much! Your feedback is appreciated!
My chevy lumina 95 3.1L V6 has its alternator's charging output varies between 13V. to 14V. during a day of normal driving. Is it okay or not? Note: The alternator's cables are all checked fine. Thank you in advance!
